Do the same things I mentioned in the other thread you started.
Another option is to install recovery through fastboot. Then flash a rom.

And if you have TWRP already, just flash a rom. Or restore a backup.

Hey brother, had a similar problem myself my first attempt at flashing.
Go to the LG website, click Products at the top and go to mobile and cell phones in the drop down. Then filter by carrier (since LS970 is Sprint), Sprint. Find the Optimus G, click it, click product support, software update, then download the USB drives and install. Restart your computer, plug in your phone while in either download or fastboot mode and get her fixed!
Good luck!

Do you have stock recovery? Or TWRP? If TWRP, then ADB sideload a Stock Rom and flash it.

Yes kind sire its TWRP
am on it will let you know
i do have TWRP : 2.6.0.0
If you flash with LGNPST then go into the factory recovery by holding vol-down and power together, then do a factory reset. might solve your problems but you will lose everything on the sd card (sounds like you might have already) but after that you can root and unlock. someone correct me if i'm wrong, i only used LGNPST once

but after a while somehow prseed correct buttons and got into bootloadera dn then twrp

won't let you get into download mode holding both vol buttons and pluggin in usb? weird. If it lets you get into twrp, go to advanced and use the file manager to see if the backup was moved to '/sdcard0/0/twrp/whatever' because if you flash aosp then it does some weird emulation and moves **** all over

looks like many folders are totally empty
Are you making sure the phone is completely off by holding the power button for 60+ seconds then trying? A few seconds of the power button won't shut it off all the way. Unplug it and holds power for a good full minute then try download mode

LGNPST will wipe all partitions except /data which is why they say to do a factory reset in Stock recovery. After that you can use engines root guide to root and unlock and install twrp again

lgnpst couldn't flash completely , it didnt finish
so if at all i go back to stock recovery and it doesnt help , then what will i do ?
EDIT : BTW the /data folder is also empty
If your phone reboots at either 67 or 85% I believe it's finished. If flashing with LGNPST doesn't work I'm working on uploading the LG flash tool which will wipe and flash back to out of the box clean to the point you have to reactivate it on sprint network lol

LGNPST rarely wipes SD. It will also keep your data. That's why we have to wipe to get it to boot up. Factory reset in stock recovery will wipe SD, and everything.

to flash roms on 4.4.X you have to have a newer version of TWRP. You are on the old version. Restore from back up if you have wiped and update TWRP before flashing. It should be 2.6.3.2 the version you have has a different kernel and it will not work

Yeah I understand but a high % of people on here don't read everything before trying something. If you don't remind him that it just for reference but may differ he may try it. It would probably fail because of the locked boot loader but still just have to be careful.
One guy hard bricked his V500 by flashing V510 stuff over it. Now he had to trick it to receive OTAs but it is possible.

Ioroot 25, will do the trick. Airplane mode, USB debugging on. No recovery necessary. Then install auto-rec and run.

[Q] [HELP] Phone Soft Bricked, no tool working

Well, let me explain what happens...
I have an LG Optimus G, which I've rooted. I wanted to install CWM, but I didn't read at the tutorial that this wouldn't work with the bootloader locked. I restarted the phone and it tells me a "Secure Booting Error".
I can access Download Mode, and there I've tried the LG Mobile Support Tool, which always tells me that "Battery is low". I've tried unplugging the battery, but the same. If I could bypass this error, probably I could have again my phone alive. I tried using also the FlashTool, but it says the kdz is corrupt (>1GB) and when doing a test upgrade, it shows again the battery trouble.
What should I do? Shall I buy a new battery? Or is there any other method to bypass this message?
Thanks for your time and your patience.

It's not just a key combination... To enter download mode, you should turn off your phone (hold Power for >15 sec), then hold both Volume buttons and connect the phone by a USB cable to your computer. Is this exactly what you are doing? And it's not working?

It's not just a key combination... To enter download mode, you should turn off your phone (hold Power for >15 sec), then hold both Volume buttons and connect the phone by a USB cable to your computer. Is this exactly what you are doing? And it's not working?

I could enter into Download mode before and KDZed but i think something went wrong after installing Sling Rom 2.1 with 180L patch, that's why its not working anymore

After Lg logo with Secure boot Error phone goes directly to CWM recovery. My original model is F180L and I was using Sling Rom 2.1 with 180L Patch

So i think you should flash original KDZ for your LG variant, and from clean rom start flashing custom roms.
PS.: Sorry its one month but i couldnt write before, i hope you have resolved problem, or i helped rit now.

Thanks mate, I had managed to flash using LG FlashTool 2014 version. My phone is alive now. Thanks for your help

So im happy that it worked

Nuke your laf partition for a way to get into fastboot via the button combination

Note 1: This is probably only aimed at developers
Note 2: I have done this with my VS980 with the 12B aboot and it works as intended, but I cannot say for sure if every G2 variant is like this!
The partition /dev/block/platform/msm_sdcc.1/by-name/laf is LG's special partition for restoring the device to factory state with the Windows recovery tool. Upon further inspection of this partition, it's just a normal boot image, with a kernel and ramdisk like every boot/recovery image.
Unfortunately, LG decided to remove ways to get into fastboot, and the only way to get into fastboot is to nuke your boot or recovery partition, so that aboot will search for a kernel and when it doesn't find one, it will boot into fastboot. So I got the idea that since the laf partition is just a normal partition to boot kernels from, why not run the command
Code:
dd if=/dev/zero of=/dev/block/platform/msm_sdcc.1/by-name/laf
Which will make aboot fail when attempting to boot from the laf partition, and set the boot_into_fastboot variable to true, and boot into fastboot!
I hope this helps somebody fastboot flash a recovery instead of using LG's proprietary service, which wipes your internal storage on restoration.
Also, I tried installing a non-lokified custom boot image to the laf partition, it still fails with a secure booting error, so aboot checks the laf partition for a signing key :/ but yay, fastboot!
Good God I wish I had seen this a week ago. Because of that stupid partition, I've been without a phone for almost a week. I'm in a state where I can't get past initializing download mode, loading recovery mode, and the LG logo. If I could get to fastboot I'd be set. Instead, now I'm waiting for my replacement phone to come in and have been since Tuesday night (it comes in tomorrow at 2pm EST)

Wow that's not good. Care to share how you got yourself into that situation? Was it because of the 12B aboot?

The ZVC aboot can be downgraded to ZV7 for loki support, but it breaks download mode, and just keeps loading forever.
Somehow, he lost recovery and boot, on top of a ZVC laf on downgraded aboot.
A few people got into this situation before we just started downgrading our laf partitions.

Oh man I think that's 100% unrecoverable. Unless there's a certain cable or button combo we don't know about that can put the device in qhsusb_bulk mode where the partitions are listed in /dev/sd* I think it's hosed.

Only way to force bulk mode afaik is this guy. http://downloads.codefi.re/savoca/autoboot/autobulk.zip But I can only confirm for ls980.
I haven't found any way to do anything with it at all, really. No bulk, nada. No boot, no recovery, no download mode, no adb, no bulk, not a single thing. LG is going to have a blast JTAG'ing this brick when they get it back.
Luckily, Sprint replaces phones with software issues for $75, or free if you have the repair service add-on/insurance. It's not same day replacement though. Mine died Tuesday night and I get my new one in twelve more hours.

Savoca ...as usual, you're my hero. I'm keeping that zip handy in case I get ready to do ANYTHING that could result in a hard brick. Bulk, download or fastboot mode would solve all of my problems right now, so for my replacement phone I intend to have at least two of those three options open any time I'm doing something risky.

Without some sort of software flashed beforehand that forces fastboot in place of download mode, or bulk always on, it's totally unrecoverable.
My primary mistake in all of this was one terrible assumption: I assumed that since the G2 is internally almost the exact same phone as the nexus 5 that there would be some way to get to fastboot mode even if recovery and download mode were both hosed. LG proved me wrong. Very wrong. I even tried applying various resistors to the charging pins hoping I'd find a fastboot combo ala Samsung's USB jig. No dice.

Wow good find. I was looking for a way to reliably do this about a month ago.
Is this just for V980 or will it work for other models (D802 ?)

This is the exact problem I have. No recovery, no download mode. I hope there will be a way to fix this even if I have to open the phone to solder something up.
Hey....using a root file explorer, I found the laf (Is that LG trying to be funny?) partition on my LG Optimus L90! I wonder if this would work.... Hmmm.

I don't know anything about that device :/
If it's coded by aboot to boot into fastboot if the partition is nuked then it should theoretically work

Hello. This would be very useful for me on the P875h. Trying to compile CWM, and every time I boot into recovery (now my build boots, but no LCD on) I get a wipe_data flag! Can't find the source of it!
But there is no partition with the name laf.
Can someone tell me what is the block for this partition? (mmcblk)
And what size is it?
Thankx!
